Enable a piece of code as the project starts

Only three steps are required:

1. Create a servlet for your code and rewrite the init () method. The content is the code or method interface to be executed;

2. configure it in the project's web. xml file. (For example, if the servlet name is ftpfileServlet

<Servlet>

<Servlet-name> ftpfileServlet </servlet-name>

<Servlet-class> sdcncsi. ict. jmt. ftpfileload. ftpfileServlet </servlet-class>

<Load-on-startup> 2 </load-on-startup>

</Servlet>

<Servlet-mapping>

<Servlet-name> ftpfileServlet </servlet-name>

<Url-pattern>/servlet/ftpfileServlet </url-pattern>

</Servlet-mapping>

The url-pattern changes with the change during creation. The integer value of load-on-startup is the priority, which is described by google .)

3. Start.
